AC delete and charcoal canister issue

[stallings.sean]

I am new to the forum but have been reading the threads for a while now.
I just got my 78 olds cutlass supreme brougham and am doing a little work on it.
The car has been sitting for 6 years and I just got it running and am not doing a little work to keep it running and clean out the engine compartment. This car has a 260 olds engine.

First question. I removed the AC unit, the pumps, condenser, heater core, all the vents in interior, the whole shebang. I assume the little ball on the right side wheel well with 2 vacuum lines (purple and black) can go as well. Should I then plug the whole where the black line goes into the back of the intake manifold?
I am making an AC delete panel to clean up that side of the firewall and seal the outside from the inside.
There is a small green wire that is attached to a wiring harness that has a red wire and another green wire that just kinda hangs there, I think it used to plug into the AC unit somewhere. The green wire goes right above the fuel pump and plugs into a little cylinder that is bolted to a bracket on the carb. since the wiring harness isnt connected to anything, can I unplug that little green wire and disconnect the cylinder. I dont know what that cylinder does or if I need it anymore.

In regards to the charcoal fuel filter. It was flooded with gasoline, I think I need to rebuild the carb, will the cylinder dry out and be fine? Id like to bypass it but from what Ive read some people say yes, some say no. Do I really NEED it? A buddy of mine took it out of his AMC once and didnt notice a difference I didnt know if I can just bypass it and plug the vacuum lines.
Ill probably keep it in the car, in saying that, there are 4 hoses coming out of it, 2 come out on top of each other, I have no idea where the small one goes. I have it plugged right now with a screw and I think it goes to the manifold but Im not sure, I looked and cant find where it should plug into.

If you dont understand my questions, Ill take some pics and post.
Thanks.

I don't have your answer for you but I've been thinking of taking my A/C out plus the charcoal canister so as to clean up the engine bay of my 350 in my Caballero. I looked at the instructions that AC Delete.com has on the GM G-body AC Delete Cover and just wanted to know if you bought one of there kits for this job? I can't do much work myself with a bad back at 66 here now but since this is my show car want to clean up the engine bay.
I've not seen one older car at all the car shows I've been going to that have the charcoal canister still in, so I will only assume for now you can just take it out????? Michael

Hey Michael, thanks for the reply, if youve seen it without the canister at least I know its doable.
I did not buy one of the kits from ACdelete.com. I did look at the site but I just did the removal myself. Are you planning on removing the AC and leaving the heater in there or taking the whole AC/Heater system out? if you take out the whole system then you are able to remove the vents from under the dash and that saves quite a bit of room under there. I am not planning on driving the car in the winter and would like to have a summer cruiser, sleeper so I decided I didnt really need the heater in there, it was also leaking and that was not a mess I wanted to deal with, just easier to take the whole thing out.
It was not a particularly hard job, I did it in 2 days, under hood in 1 and vents the other. It is a back breaking job if you dont take the hood off but sending it to someone might not be a bad idea. My car had been sitting for 6 years so a lot of the bolts were stuck on so Im sure it wouldnt be that hard if your engine compartment looks in decent shape. Being that its your show car, Im assuming everything looks pretty good under there and it should be somewhat easy to get off.
Let me know if you have any questions.
Ill post a pic when I get the panel made and put on.

Good luck with your car.

Hmm. I don't have an answer to the canister question, but i did remove mine. I have an 88 Monte Carlo SS. What i did can't really compare to what you are doing though, i rebuilt the entire car. New fuel lines from the tank up, exhaust, engine, trans, rear end, Entire A-arm assembly's. I do know you can remove it though

Also, the vacuum ball, i THINK this controls the air flow of your vents

Thanks Camaroadam.
Assuming you have a 4bbl carb on your SS. I have a rochester 2bbl on mine. One the charcoal tank there is a hose that goes to a fuel line (assuming its the vapor line) and a hose that comes from the carb to the canister. Do you just have your fuel vapor line from the gas tank hooked onto your carb? I assume that would mean that any additional vapor would dump back into your fuel tank.
You, having a monte, might have a different set up but Im thinking that might be what I try.

Prior to whatever year the charcoal canisters appeared, the gas tank vented to atmosphere. If you walked past a vented car on a hot summer day, you smelled gas fumes. To keep these fumes out of our air, the car makers figured out that activated charcoal (same as a fish tank filter) can absorbe 100 times it's weight in gas fumes. So they ran a vent line from the gas tank to the canister and a line to the float bowl to capture and hold the fumes. When the motor starts, the fumes are drawn into the carb to be burned. That is why there is a filter on the bottom of the canister to flow fresh air over the charcoal and later cars have a solenoid to control the release. The gas cap that used to be vented, was now sealed so fumes cannot escape. This is a passive system that in no way affects the performance of the car.

Actually no i don't, From my sending unit in the tank, i capped the smaller line that i think was called a vapor return line? My fuel pump only has one inlet and one outlet. As for the vacuum ball/ canister, all of that was removed and almost all of the stock components on the car have been replaced.
